There are few iso and british standards available that provide symbols and best practices to draw pfd and p id such as isa s5 1 bs 5070 and iso 10628.
Liquid ring vacuum pump p id symbol.
Liquid ring vacuum pump.
Each symbol is accompanied by a unique reference e g.
They are typically used as a vacuum pump but can also be used as a gas compressor the function of a liquid ring pump is similar to a rotary vane pump with the difference being that the vanes are an integral part of the rotor and churn a rotating ring of liquid to form the compression chamber seal.

See below our most common list of p id symbols for pumps with their meaning.
Positive displacement pump 01.
Through our ongoing commitment to innovation product research and development nash continues to.
The symbols for various types of rotary equipment such as a centrifugal pump vacuum pump and also positive displacement pumps such as gear and screw types.
The impeller 4 with the blades is located in the cylindrical housing 5.
The isa s5 1 iso 10628 and bs 5070 cover the standardization of p id symbols and guide process engineers in their plant design activities.
Piping and instrument diagram standard symbols detailed documentation provides a standard set of shapes symbols for documenting p id and pfd including standard shapes of instrument valves pump heating exchanges mixers crushers vessels compressors filters motors and connecting shapes.
Nash liquid ring vacuum pumps are a reliable and durable solution for challenging process applications.
Positive displacement pump 02.
The symbols for vacuum pumps should always be so positioned that the narrowing lines point to the side of higher pressure.
This details the specification which the equipment should conform to.
P 001 which will detail the equipment design at each location in a separate process datasheet.
P id symbols exist for all major components and lines such as valves vessels instruments pumps compressors and towers.
Environmental pumps do not require an oil change filter oil pans.
As shown in above figure in a liquid ring vacuum pump the pumped gases vapors air is a mixture of gases are sucked via the inlet connection 3 into the pump motor unit and pushed out via the discharge connection 1.
Our liquid ring vacuum pump design was the first of its kind at the turn of the 20th century and has been an industry leader ever since.
Centrifugal pumps 04.
